Title: Improvements relating to thermionic amplifiers
IPC: H03F1/50
Filed: 1934-03-01
Abstract: 419.914. Valve amplifying circuits. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Dome, R. B. ; 13, 9th Street, Schenectady, New York, U.S.A.) March 1, 1934, No. 6591. Convention date, March 1, 1933. [Class 40 (v).] In an amplifier for television or like signals, wherein a valve 1 has a coupling which includes a condenser 6, the loss of amplification at high frequencies is counteracted by means of a backcoupling circuit which neutralizes the effect of the inherent capacity of the valve. To this end an inductance 8, which is negligible at low frequencies but effective at higher frequencies, is located in the grid circuit and coupled to an inductance 9 which is fed through a neutralizing feed-back condenser 11 whose capacity is equal to the grid-to-anode capacity of the valve. The inductance 9 is shunted by a variable condenser 10 whose capacity is equal to the grid-to-cathode capacity of the valve. In a modification, (Fig. 1, not shown), the coils 8, 9 form an autotransformer with the grid-coupling resistance 3 tapped off its central point. Specification 366,683 is referred to.

Patent GB-554282-A (GB)
Title: Improvements in or relating to automatic gramophones
IPC: G11B3/38
Filed: 1942-05-19
Abstract: 554,282. Automatic gramophones. INDUSTRIAKTIEBOLAGET LUXOR. May 19, 1942, No. 6785. Convention date, June 25, 1941. [Class 40 (ii)] In gramophones provided with automatic record-changing devices for records of mixed diameters, the pick-up arm E is arranged to be moved from its outermost position inward over the record to be played a distance at least sufficient to bring the needle 10 over the starting groove of the smallest diameter record (in the form shown slightly further inwards), and means are provided to cause the pick-up arm to be moved back, if it is too far in, until the needle is over the starting groove of the record, whatever the diameter of the record. As shown, a roller 1 is mounted on one end of a spring blade 2 attached at its other end to the pick-up arm by a pivot 3. The roller end of the blade is 'guided in a bayonet-like slot 5 in a plate 6 on the pick-up arm ; and a lever 7 pivoted on a horizontal pivot 8 on the pick-up arm rides at one end on a fixed bar 9 and overlies the spring blade 2 at its other end. During the play of a record, the blade 2 is held by a spring 4 at the upper end of the wide part of the slot 5, Fig. 4, and the roller I is above the surface of the record 12 engaged by the needle 10. When the playing is completed, the pick-up is lifted in known manner and moved outward, and then moved in again to play the next record. The lifting of the pick-up arm causes the lever 7 to be deflected by the bar 9 and to depress the blade 2, which is then moved into the narrow part of the slot 5 by the spring 4, so that when the pick-up arm is again moved in and lowered, the roller 1 touches the record 12 before the needle 10. The axis of the roller is slightly inclined to the radius from the centre of the turntable so that the rotation of the turntable causes the pick-up to be moved outwards until the roller 1 drops over the edge of the record or the turntable. When this occurs, the needle engages the record and play beings. The roller 1 is forced away into the wider part of the slot 5 and is lifted up by the spring 4 back to the position shown in Fig. 4. The records to be played may be stacked on the turntable and discharged therefrom one at a time after being played. The turntable A may be of larger diameter than the records, so that when all the records have been played and discharged, the roller 1 will be engaged by the turntable and impart an extra outward displacement to the pick-up arm. This extra displacement or the resulting drop of the roller 1 over the edge of the turntable is used to actuate a member 14 to apply a brake or to switch off a driving motor. Alternatively, the turntable may have a groove of opposite pitch to the records, so that when no record is present when the pick-up is lowered, the engagement of the needle with this groove causes the pick-up to be moved out and the roller to drop over the edge of turntable.

The clamping means may comprise an eye 16 secured to one of the extremities 13 so as to pass through a hole 17 in the adjacent confronting extremity 13, and a wedge 18 which is driven into the eye 16. In an alternative arrangement the extremities 13 may cross each other in scissor fashion with a wedge driven between them. The plate 11 may be provided with two opposed extensions each having a lateral extremity with clamping means, the extensions being adapted to embrace both flanges of the I-sectioned arch member.

Abstract: 394,442. Waterproof abrasive &c. articles. HADNAGY, Z., BOUILLARD, A., and AUBY, A., 73 bis, Rue de Villiers, Neuilly-sur-Seine, France. March 8, 1932, No. 6937. Convention date, March 14, 1931. [Class 60.] Waterproof abrasive articles, for example, sand paper, emery cloth, &c., comprise the use of an adhesive consisting mainly of material elastic at normal temperature, which melts or softens at a temperature of about 100‹ C., and which solidifies in a few seconds on natural cooling. Examples of substances suitable are oils treated with sulphur, stearin pitch, guttapercha, balata with or without oil, partially oxidized or polymerized oils, for example, linoxin, mordant, or blown oil, naphthalene, sulphur, and to these may be added resins, wax, or a mixture of synthetic resin and natural resin. In the production of abrasive paper &c., the paper &c. 1 passes over guide rollers 2, 3 to a cylinder 4 which applies, from a bath 5, the waterproofing substance to the back of the paper. The paper then passes to a cylinder 8 beneath a hopper 9 containing the adhesive substance and applying it to the paper, the cylinder 8 being heated by gas jets 10 &c. As the paper passes from the hopper, it passes under an electrically heated scraper 12 and then over an inclined table 13 heated to above 100‹ C., whereon the abrasive grains are supplied from a sifting device 16 agitated by a lever 19 and an eccentric 17. After leaving the table, the paper is subjected to the action of hammers 20 operated by a cam 22 to remove excess abrasive ; the paper is then cooled and cut into sheets. The Specification as open to inspection under Sect. 91 comprises also the application of the process to the production of oilcloth and other articles with a waterproof coating.
